Rafe Spall will be chasing spooks in his new TV role as Harry Price: Ghost Hunter.
The Life Of Pi actor has signed up to star in the feature length drama for ITV about a fraudster medium and ghost hunter who is given a chance to turn his life around by taking on a new case.
The period film, set in the 1920s, is based on the novel The Ghost Hunters by Neil Spring.
Fact and fiction will be combined to tell the story of famous British ghost hunter and sceptic Harry Price.
Spall said: "I'm delighted to be portraying Harry Price for ITV. It's a fantastic piece of history that has mass appeal and I can't wait to start filming."
He will be joined by Downton Abbey's Cara Theobold as maid Sarah Grey, who helps Harry with his investigation into the supposed haunting of the home of a local MP.
Harry Price was a psychic researcher who investigated paranormal phenomena and worked to expose fake spiritualists.
Filming is about to begin in London.
